Trauma focused-cognitive behavioral therapy training effectiveness in promoting professional development of psychotherapists working with unaccompanied minors in Greece: a non-blinded randomized control trial.

The need to develop psychotherapists' skills to respond to current treatment challenges, such as addressing trauma due to the refugee crisis, is increasing. However, there is a dearth of evidencebased training for psychotherapists who work with refugees, especially in frontline countries. A randomly selected sample of 80 clinicians working with unaccompanied minors (UAMs) in Greek accommodation centers nationwide participated in an intensive trauma-focused cognitive behavioral therapy (TF-CBT) training (n=44) or a control-group (n=36) and completed the Professional Quality of Life Scale, the Work and Meaning Inventory and a questionnaire to assess knowledge and therapeutic skills, in pre-andpost measurements.

Overview of the Alaskan Layered Pollution and Chemical Analysis (ALPACA) Field Experiment.

The Alaskan Layered Pollution And Chemical Analysis (ALPACA) field experiment was a collaborative study designed to improve understanding of pollution sources and chemical processes during winter (cold climate and low-photochemical activity), to investigate indoor pollution, and to study dispersion of pollution as affected by frequent temperature inversions. A number of the research goals were motivated by questions raised by residents of Fairbanks, Alaska, where the study was held. This paper describes the measurement strategies and the conditions encountered during the January and February 2022 field experiment, and reports early examples of how the measurements addressed research goals, particularly those of interest to the residents.

A Finnish Meteorological Institute-Aerosol Cloud Interaction Tube (FMI-ACIT): Experimental setup and tests of proper operation.

The Finnish Meteorological Institute-Aerosol Cloud Interaction Tube (FMI-ACIT) is a multi-purpose instrument for investigating atmospherically relevant interactions between aerosol particles and water vapor under defined laboratory conditions. This work introduces an experimental setup of FMI-ACIT for investigation of the aerosol activation and the droplet growth under supersaturated conditions. Several simulations and experimental tests were conducted to find out what the proper operational parameters are.
